Soon after this picture of Charlotte Casiraghi appeared, Glenn Beck announced that he was starting his own line of jeans. Classic denim makes for strange bedfellows.

In one corner we have Casiraghi, granddaughter of Grace Kelly and mainstay of the International Best Dressed List. Just when you thought there was no way denim on denim could ever be pulled off successfully, Casiraghi shows up in the front row at Gucci's Spring 2013 show in Milan. Her secret may simply lie in the eternal mystery of insouciant French style, but her tailored Gucci resort blazer, classic denim trousers, low ponytail, and discreet gold hoops might be contributing factors. True, Casiraghi could make acid wash elegant, but, still, these are jeans to aspire to.

In the other corner is conservative political commentator, radio host, and, yes, denim designer Glenn Beck. His 1791 Supply & Co. line of American-made jeans is sold only online and is made in limited quantities. He claims to have worked on its development for a year, weighing in on all aspects of the classic and straight cuts. The line is named for the year the Bill of Rights was added to the Constitution.
